6300 Rev. H1 User’s ManualSECTION 1 : INTRODUCTIONThe model 6300 is a high accuracy automated pressure controller, specifically designed for controlling air dataparameters such as altitude, airspeed, Mach and climb. This instrument can also be used to control pressuresin units of inHg, mbar, psi, mmHg and kpa. The 6300 is equipped with internal pressure and vacuum pumps.The Remote unit is used to interface with the Main unit. The small size of the Remote unit allows it to be usedin the cockpit of an aircraft.The 6300 has two high accuracy transducers that measure pressure in the range of 1 to 32 inHg absolute on theStatic output, and 0 to 30 inHg differential on the Pitot output. These transducers are designed to accuratelymeasure the pressure of dry air over an ambient temperature range of -40oC to 80oC. The high accuracy of thePitot transducer makes it ideal for checking the low airspeeds typical in helicopters. The high accuracy of theStatic transducer makes the 6300 fully RVSM compliant.The 6300 allows the user to control altitude in feet or meters, climb in feet per minute or meters per second.Airspeed can be controlled in knots, mach, km/hr and mph. Airspeed-rate can be also be controlled in theseunits. The 6300 also allows the user to control EPR on the Pitot output.The model 6300 features programmable limits on altitude, airspeed, airspeed rate, mach number, and climbrate. These limits are checked during data entry and thereby prohibit entry of erroneous target values. Theselimits are also checked continuously during operation, and if any of these is exceeded, the unit automaticallytakes abortive action.The user has the ability to program into the 6300 a profile of set-points to be controlled in a sequence. Oncesuch a profile has been setup, the user can command the unit to move from one set-point to the next simply byusing the Up-arrow key. Up to 50 points can be stored in one profile. The 6300 can store up to 15 such profilesin non-volatile memory at any one time.Calibration of the unit is required only once a year. This process is the only scheduled maintenance functionrequired on the 6300.The standard version of the model 6300 operates on AC power and comes with an RS232 interface. Optionsinclude an integrated battery which lasts up to 8 hours, internal heaters which allow the unit to operate downto -40oC, and an altimeter-encoder interface.The 6300 has built-in Wi-Fi capability which allows for wireless remote operation using an Apple iPad orandroid tablet.125-9106BPage 7

6300 Rev. H1 User’s ManualSECTION 2 : CONTROLS & CONNECTIONS2.1MAIN UNIT, TOP PANELThe model 6300 top panel provides easy access to all the connections. Please refer to Figure 2.1(A) and 2.1(B)shown on previous two pages.[1]AC INPUT connector:This is a 3-pin male circular connector. A power cord is provided with the 6300. The circular connector end ofthe power cord needs to be connected here. The power requirement of the 6300 is 90-260 VAC, 47-440 Hz witha maximum power consumption of 100 VA (200 VA with heaters). The pin-out of this connector is providedin Appendix CCaution: Connecting incorrect power to the 6300 will cause considerable damage[2]AC Fuse :A 5x20 mm fuse is located inside the fuse holder. This time-delay fuse, with a rating of 2.0 amps, 250 Volts,limits AC power to the unit.[3]AC On/Off Switch :This toggle switch connects (or disconnects) AC power between the AC INPUT connector and the 6300. Evenwhen this switch is ON, the 6300 becomes fully operational only after the Power key located on the keypad ofthe Remote Unit is pressed for a minimum of 3 seconds.When an internal battery is included, the battery-charging circuits inside the 6300 become active when the ACOn/Off switch is turned ON.When internal heaters are included, the heater-control circuits inside the 6300 become active when the ACOn/Off switch is turned ON.[4]Battery Fuse :This fuse is installed only if the optional battery is included. A 5x20 mm fuse is located inside the fuse holder.This time-delay fuse, with a rating of 10 amps, 250 Volts, limits battery power to the unit.125-9106BPage 10
6300 Rev. H1 User’s Manual[5]Battery On/Off switch:This switch is installed only if the optional battery is included with the system. This switch connects (ordisconnects) the battery from other circuits within the 6300. If AC power is not available, turning this switchOn allows the unit to operate on internal-battery power.In situations where AC power may be intermittent, it is advisable to keep the Battery On/Off switch in the Onposition. This will allow the internal circuits to automatically switch to battery power when AC power is lost.Caution: When the unit is not being used, the Battery On/Off switch must be in the OFF position. Leavingthis switch ON will drain the battery since some internal circuits will be active when this switch is ON.[6]Remote Unit connection:Using the 50-foot remote cable, connect the Remote unit to the Main unit through this 10-pin circular connector.It is recommended that this connection be made prior to applying power to the 6300. If this cable isdisconnected, the 6300 stops operating.[7]Emergency Vent Valve, "Pitot Cross-bleed" :In the event that the 6300 is in-operable due to a malfunction or due to loss of power, it is possible to vent thePitot system manually. This is done using the metering valve labeled “Cross-bleed”. This valve is a positiveshut-off valve. Opening this valve slowly will equalize the pressure between the Pitot and Static systems(causing airspeed to be at zero).Since opening this valve transfers pressure from the Pitot system into the Static system of the aircraft, whileopening this valve, care must be taken to vent the Static system simultaneously (if necessary), to prevent thealtimeter in the aircraft from going below minus-1000 feet. Also, care must be taken not to exceed themaximum value of the Climb indicator in the aircraft.Once airspeed is down to zero, this valve must be opened completely, to ensure that airspeed stays at zerowhile the Static system is vented to ambient (using the Static vent valve).Caution: This valve is for emergency use only and should not be used during normal operation. Whenemergency venting is completed, this valve should be closed immediately.Caution: This valve should not be tightened at all past its stop. It seals before it hits the stop. Even fingertight beyond the stop may damage the seat of the valve, causing it to leak constantly.[8]Emergency Vent-Valve, “Static Vent”:125-9106BPage 11
6300 Rev. H1 User’s ManualIn the event that the 6300 is in-operable due to a malfunction or due to loss of power, it is possible to vent theStatic system manually. This is done using the metering valve labeled “Static Vent”. This valve is a positiveshut-off valve. Opening this valve slowly will vent the Static output of the 6300 to ambient pressure.While venting, care must be taken not to exceed the maximum value of the Climb indicator in the aircraft.Also, before venting the Static system to ambient, the Cross-bleed valve must be opened to ensure that airspeedis zero.Caution: This valve is for emergency use only and should not be used during normal operation. Whenemergency venting is completed, this valve should be closed immediately.Caution: This valve should not be tightened at all past its stop. It seals before it hits the stop. Even fingertight beyond the stop may damage the seat of the valve, causing it to leak constantly.[9]Static port :The Static port of the tester is provided with a #4-AN fitting. This port must be connected through a hose tothe Static port of the aircraft. The hose must be connected after performing the Self Test on the 6300. The hose,once connected, must not be disconnected while the aircraft Static system is not at “Ground” level.Caution: Do not connect the Static hose to the Static port before performing the Self Test.Caution:Do not disconnect the Static hose from the Static port unless the aircraft Static system is at“Ground” level and the tester has been turned Off.[10]Pitot port :The Pitot port of the tester is provided with a #4-AN fitting. This port must be connected through a hose tothe Pitot port of the aircraft. The hose must be connected after performing the Self Test on the 6300. The hose,once connected, must not be disconnected while the aircraft Pitot system is not at “Ground” level.Caution: Do not connect the Pitot hose to the Pitot port before performing the Self Test.Caution: Do not disconnect the Pitot hose from the Pitot port unless the aircraft Pitot system is at “Ground”level and the the tester has been turned Off.125-9106BPage 12
6300 Rev. H1 User’s Manual[11]Indicator LED’s :‘Ready’ LED: This green LED provides several indications as described below.a.When the unit is ready for use, the LED is steadily On.b.When the Remote is not connected, the LED blinks two times every 2-secondsc.When the temperature is too low for operation (on units without heaters), the LED blinks once every2-seconds.d. After the unit is ready for use, when the Power key on the Remote is pressed, the LED blinks rapidlywhile the Power key is held down. If the Power key is held down for more than 3 seconds, either aturn-On or Turn-Off condition is ‘detected’ and the LED blinks slowly for 5 more seconds, duringwhich the user must release the Power key.‘Heaters’ LED: On units equipped with internal heaters, this yellow LED will turn On while the heaters areOn. The LED may stay On even after the Ready LED comes On.‘Low-Batt’ LED: On units with an internal battery, this yellow LED will turn ON when a low-battery conditionis detected. After this LED turns ON, the user will typically have 15 to 20 minutes before the unit automaticallyturns OFF due to total discharge of the battery. The Remote unit also displays a low-battery condition as awarning message.‘Charging’ LED: On units with an internal battery, this red LED will be ON while the battery is being charged.[12]RS232 interface connector:This connector is accessed by opening the “Interface Connectors” access panel.The connector is a standardDB-9 female connector used for a serial RS232 interface. It can be connected directly to the “COM” port of astandard PC to allow communication. This port is normally used for downloading “profiles” from a computer.Other remote communication with the 6300 is also possible through this interface.For more details on downloading profiles, please refer to Section 4. For more details on communication withthe 6300, please refer to Section 8. The pin-out of this connector is provided in Appendix C.[13]Encoder interface connector:This connector is accessed by opening the “Interface Connectors” access panel. If the Encoder option isincluded with the tester, this connector will interface to an altimeter encoder and enable the 10-bit Gray codeto be displayed on the Remote unit. For more details, please refer to Section 3.10.9. The pin-out of this connectoris provided in Appendix C.125-9106BPage 13

Whenthe Remote unit is Off and the Ready LED is On, pressing the Power key for 2 to 3 seconds will turn-On the6300. The display takes another 2 seconds to come on. The Power key may be held down until the displayturns On (a total of about 4 seconds), but must be released within 2 to 3 seconds after the display turns On (toavoid going into the Power-Off cycle).When the Remote unit is On, pressing the Power key for 3 seconds will turn the 6300 and the Remote unit Off.After the unit turns Off, the Power key must be released within 2 to 3 seconds, to avoid going into the PowerOn cycle.[3]Connector:This circular connector is used to connect the Remote unit to the Main unit through the Remote cable. TheRemote unit must not be disconnected from the Main unit while the unit is operating. This will cause the unitto turn Off.[4]Tilt-stand:On the rear of the Remote unit, a tilt-stand has been provided which allows the Remote to be tilted to aconvenient viewing angle.125-9106BPage 16
6300 Rev. H1 User’s ManualSECTION 3 : OPERATING THE 6300This section provides all the details required to operate the 6300. It is highly recommended that the userread through this section before operating the 6300. After understanding these details, the user shouldrefer to the ‘Typical Use’ chart shown in Figure 5.1, which outlines a step-by-step process of using the 6300with an aircraft.3.1START-UP Open the Pitot and Static ports to ambient by removing the blue caps. Connect the Remote unit to the Main unit using the Remote cable. Connect AC power to the Main unit using the power cable. Turn On the AC On/Off switch on the Top Panel of the Main unit. Wait for the Ready LED to turn On. Press the Power key on the Remote for about 4 seconds until the display turns On. Release the Power key. After the sign-on screen, the display will appear similar to that shown inFigure 3.1 (next page).Note: The pumps will be Off. The pumps turn On only if one of the outputs is in either Control orLeak mode. The pumps also turn On during Self-Test. Perform a Self-Test by pressing the TEST key. The message ‘Open both ports to ambient, then pressGO. Press CANC to exit’ will be displayed in the Lower section of the display. Make sure both portsare open to ambient, then press GO. The Self-Test takes about 2 minutes. When it is completed, the message ‘Self-Test successful. PressCANC to exit’ will appear on the last line. Press CANC.The following sub-section provides details of the parameters shown on the main operating screen and howto modify these parameters.Later sub-sections provide details on how to perform various other functions of the 6300125-9106BPage 17
6300 Rev. H1 User’s ManualFigure 3.1: Main operating screen3.2MAIN OPERATING SCREENPlease refer to Figure 3.1. There are 17 different items (indicated in red) shown on this screen. Numbers 1to 7 on the left side, refer to the Pitot-ouput parameters. Numbers 8 to 14 on the right side, refer to theStatic-output parameters. Number 15 points to the power status. Number 16 points to a typical symbolindicating a key number (as shown, key # 1 ). Number 17 points to the ‘Messages’ section of the screen.Details of each item follow.[1]Pitot unitsThe selected Pitot units are displayed here.

6300 Rev. H1 User’s Manual[2]Pitot Actual valueThe Actual value (actual pressure converted to selected units) being measured or controlled at the Pitotoutput is displayed here in the selected Pitot units. The displayed resolution of this value depends on theselected units and is shown in the table below. This Actual value is updated every 250 msec.DisplayedResolutionPitot unitsknots0.1Mach0.001km/hr0.1mph0.1Pt inHg0.001Qc inHg0.001Pt mbar0.01Qc mbar0.01Pt psi0.001Qc psi0.001Pt mmHg0.01Qc mmHg0.01Pt kpa0.001Qc kpa0.001EPR0.001Important Note: When Pitot units are knots, km/hr or mph, and both ports are open to ambient, theActual airspeed value could be as high as /-8 knots (instead of the expected 0 knots). This is still withinthe specified accuracy of /-0.003 inHg. Also, this does not mean that airspeed indications will be offby /-8 knots over the entire range of the airspeed indicator. Because of the extreme sensitivity ofairspeed to pressure at very low airspeeds, an error of 8 knots at ambient will translate to an error ofonly 1.5 knots at 20 knots and only 0.6 knots at 50 knots. The error will decrease further as knotsincreases.[3]Pitot Target valueThe target value that the user desires to achieve on the Pitot output is displayed here. When the Pitotoutput is in Control mode, the 6300 will automatically adjust the Pitot Actual value to match the PitotTarget value. The resolution of the Pitot target value is the same as the resolution of the Pitot Actual value.How the user can change the Pitot Target value is described in Section 3.4.[4]Pitot-Rate units125-9106BPage 19
6300 Rev. H1 User’s ManualThe Pitot-Rate units are typically the Pitot units per minute. If Pitot units are knots then the rate units areknots/min. However, there are three exceptions as shown in the table below. Pitot-Rate units cannot bechanged by the user.ExceptionsPitot units[5]Pitot-Rate ate Actual valueThe Actual rate of change of pressure at the Pitot output, converted to current Pitot-Rate units, is displayedhere. The displayed resolution depends on the Pitot-Rate units as shown in the table below. The ActualRate value is updated every 250 msec.DisplayedResolutionPitot-Rate .001Pitot-Rate Target valueThe rate at which the Pitot Target value ramps from one target to the next target, is determined by the PitotRate Target value. That is, if the Pitot-Rate target is set to 150 knots/min, and the airspeed (Pitot) target ischanged from 25 knots to 100 knots, the 6300 will ramp the airspeed at a rate of 150 knots/min, takingroughly 30 seconds to move from 25 knots to 100 knots.Note: On most aircraft, there is no indicator which displays this pitot-rate.The Pitot-Rate target value has the same resolution as the Pitot-Rate Actual value. How to set the PitotRate Target is described in Section 3.5.[7]Pitot Mode125-9106BPage 20
